Human DNA. Computer artwork of an anatomical human figure superimposed on a molecule of Deoxyribonucleic Acid (DNA). DNA determines a person's hereditary characteristics. DNA consists of 2 strands of sugar-phosphate groups winding around each other to form a double helix. They are connected by four types of nitrogen-containing nucleotides (bases),represented here by spheres. There are four nucleotides,these being: adenine,guanine,thymine,and cytosine. The exact sequence of nucleotides determines the genetic code | |
